NTP Client

1. NTP Client configuration is mostly the same with the Server's one, but NTP Clients do not need to receive time synchronization requests from other hosts, so it does not need to specify the line [allow ***].

[root@onlinebrands ~]# dnf -y install chrony

[root@onlinebrands ~]# vi /etc/chrony.conf

# line 3: change to your own NTP server or others in your timezone
#pool 2.centos.pool.ntp.org iburst
pool onlinebrands.io iburst

[root@onlinebrands ~]# systemctl enable --now chronyd

# verify status
[root@onlinebrands ~]# chronyc sources

2. To Install NTPStat, it's possible to display time synchronization status.

[root@onlinebrands ~]# dnf -y install ntpstat
[root@onlinebrands ~]# ntpstat
synchronised to NTP server (10.0.0.30) at stratum 3
